I'm living proof it has worked, from 10-12 how ever many years ago it was when I was going through education watching his first shows, and now I'm doing conservation work mainly with our native reptiles and amphibs, I'm in the middle of doing population distribution studies of Vipera Berus in the UK to use for predictive habitat modelling and when I sit and think how did I get here, although I was always a very "nature conscious" person, if Steve Irwin hadn't existed, I don't think I'd be doing what I am. I'd be suprised if I was the only person he affected positively through his shows.
